Angels slugger Mark Trumbo, formerly of Villa Park High, will be attending the event for the second year but will likely not compete in the contest. Trumbo participated in the 2012 All-Star Game's Home Run Derby, finishing in the top four with Prince Fielder, Jose Bautista and Carlos Beltran.

The high school round begins at 10 a.m., the pros start at noon, with the finals at 2 p.m. The participant list is below.

The event will also feature a raffle and a silent auction featuring game-used items and autographed memorabilia donated by the Angels, Trinity Bats, 44 Gloves and other organizations. Hahn, the 2010 Orange County player of the year and Mr. California, will be in attendance and also signed bats and balls.

Several players, including Trumbo, will be signing autographs. Local food trucks -- OC Burger Monster, Nacho Macho and Mustache Mike – and Chick-fil-A will be onsite.
